r8ccs is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version
r83, a Python code which contains linear algebra routines for R83 matrices (real, 64 bit, tridiagonal 3xN format).
r8col, a Python code which contains utility routines for R8COL's, that is, double precision real MxN arrays, considered as N column vectors, each of length M. The data may be thought of as a matrix of multiple columns, and many operations will be carried out columnwise.
r8ge, a Python code which contains linear algebra routines for R8GE matrices (real, 64 bit, General format).
r8lt, a Python code which contains linear algebra routines for R8LT matrices (real, 64 bit, lower triangular format).
r8row, a Python code which contains utility routines for R8ROW's, that is, double precision real MxN arrays, considered as M row vectors, each of length N. The data may be thought of as a matrix of multiple rows, and many operations will be carried out rowwise.
r8st, a Python code which contains linear algebra routines for R8ST matrices.
r8ut, a Python code which contains linear algebra routines for R8UT matrices (real, 64 bit, upper triangular format).
